Particulate matter sensor BMV080

Tiny. Noiseless. Fanless. Maintenance-free.

Coming soon: BMV080

World's smallest particulate matter sensor

The most common air quality measurement stations only provide outdoor data, which fails to deliver real-time, localized information most relevant to our health. Bosch Sensortec is addressing this issue with its new BMV080, the world’s smallest PM2.5 air quality sensor. The BMV080 sensing element measures merely 4.2 x 3.5 x 3.1 mm³ (W x L x H), which is more than 450 times smaller than any comparable device on the market. The miniscule size and fanless non-intrusive design of the BMV080 are a game-changer.

.... in volume than any comparable device on the market.

The new sensor is maintenance-free with no fan-induced dust buildup, which means that it is more reliable, and less prone to malfunction. It is a natural fit for ultra-compact Internet of Things (IoT) devices such as air quality monitors, smart thermostats, HVAC & air ventilation systems, smart air purifiers, and wearables to monitor local PM concentration in real-time to provide actionable data.

The BMV080 utilizes an innovative design based on ultra-compact lasers with integrated photodiodes. It applies sophisticated algorithms to measure the PM2.5 concentration directly in free space, without requiring a fan.

The new sensor is easily integrated into ultra-compact IoT based smart home and smart building systems to deliver air quality notifications to residents when PM2.5 levels rise above a threshold level. To take action, the resident or home automation system can ventilate, or switch on an exhaust fan or filter to clear the air.
